Tuberous sclerosis is a neurocutaneous autosomal dominant syndrome, in which angiofibromas appear in childhood in the nasolabial folds and on the central face [2]. Tuberous sclerosis (TS), or tuberous sclerosis complex (TSC), also known as Bourneville disease, is an autosomal dominant, multisystem disorder caused by mutations in the genes for the proteins hamartin and tuberin (TSC1 and TSC2, respectively). Differential diagnosis. In some cases, cerebral cortical heterotopias are visualized as hypodense nonenhancing subependymal lesions. TSC is also the leading genetic cause for epilepsy and autism.

In some cases, cerebral cortical heterotopias are visualized as hypodense nonenhancing sub-ependymal lesions. Tuberous sclerosis was classically described as presenting in childhood with a triad (Vogt triad) of: 1. seizures: absent in one-quarter of individuals 2. intellectual disability: up to half have normal intelligence 3. adenoma sebaceum: only present in about three-quarters of patients1 The full triad is only seen in a minority of patients (~30%).

The presence of multiple bilateral subependymal nodular nonenhancing hyperdense calcified lesions is relatively characteristic of tuberous sclerosis when combined with the appropriate clinical findings. Mutations in the FLCN (folliculin) gene. Please enable it to take advantage of the complete set of features! The identification of either a TSC1 or TSC2 pathogenic mutation in DNA from normal tissue is sufficient to make a Definite Diagnosis of TSC. The diagnosis of tuberous sclerosis is based on clinical features, but the distinction of types 1 and 2 requires molecular genetic analyses and the identification of mutations in the respective genes. The disease has 2 genetic loci: TSC1, found on chromosome 9q34; and TSC2, found on chromosome 16p13. The presence of multiple bilateral subependymal nodular nonenhancing hyperdense calcified lesions is relatively characteristic of tuberous sclerosis when combined with the appropriate clinical findings.

This site needs JavaScript to work properly. See tuberous sclerosis diagnostic criteria 2. Gyriform calcifications in tuberous sclerosis simulating the appearance of Sturge-Weber disease. A pathogenic mutation is defined as a mutation that clearly inactivates the function of the TSC1 or TSC2 proteins (e.g., out of frame insertion or deletion or nonsense mutation), prevents protein synthesis (e.g., large genomic deletion), or is a missense mutation whose effect on protein function has been established by functional assessment. Comparisons may be useful for a differential diagnosis: The various symptoms of tuberous sclerosis are nonspecific and many can occur as isolated findings or as part of another syndrome or disorder. When patients do not meet these criteri… 1995 Jun;118 ( Pt 3):629-60. doi: 10.1093/brain/118.3.629. Consequently, the revised criteria require tuberous sclerosis complex-associated lesions of two or more organ systems or at least two dissimilar lesions of the same organ to confirm the diagnosis.
